What version of NAMD did you use? In NAMD 2.12 or later, you cannot set hidejacobian option when you use eABF. The results always include the contribution of Jacobian term, as what Umbrella Sampling does.

Thank you Haohao.
That was my mistake. I have one more question: When I had the option ‘hidejacobian on’ on my .in file, my number of sample in the count file is close to 0. Do you know why?

Did you set scriptcolvarforces on in your .in file?

No, I don't have those files in my output folder.

Hello !
I am trying to run an eabf simulation with the RMSD as the collective variable. My calculation is running but I don’t have any output files for the eabf.
In my configuration file I added:
source ./scripts/eabf.tcl
set eabf_inputname 0
set eabf_outputname output/sod2_test.eabf
set eabf_temperature 300
set eabf_outputfreq 10000
But I don’t have any file named sod2_test.eabf in my output folder and I don’t have any errors too. Does anybody know why ?
Below is my colvar configuration file (Does this look correct for you?):

colvar {
